LEBANON, TN (WSMV) -

Investigators from multiple local, state and federal agencies continue to investigate an explosion at a Wilson County home Monday that killed two people.

The explosion happened about 5 p.m. at a home in the 500 block of Vance Lane, near Hartsville Pike, near Lebanon.

Wilson County Sheriff Robert Bryan said 74-year-old Jon Setzer was killed and 72-year-old Marion Setzer was transported by medical helicopter to Vanderbilt University Medical Center, where she died Wednesday evening.

Bryan said authorities are still in the preliminary stages of the investigation and agents returned to the scene Wednesday.

Officials said it was determined that an unknown package exploded at the home, but they have not yet revealed further details in the case.

"Any time you have an explosion like this, it's a bizarre case," Bryan said.

Mark Gwyn, director of the Tennessee Bureau of Investigation, said agents are following leads, processing the crime scene and collecting evidence to be analyzed at the TBI Crime Lab.

A reward of $8,000 has been offered for anyone who has information that leads to the arrest and conviction of the people responsible in the crime.

"It's important that we have help from the public. If anyone saw anything or believes they have information that would help us with this investigation, we ask that you call 1-800-TBI-FIND," Gwyn said.

The TBI said anyone who locates a package that they think is suspicious is urged to contact their local law enforcement agency.

McClain Christian Academy officials said classes will not be held at the school's main campus on Vance Lane Tuesday. For students who normally attend the main campus, classes will start two hours late and be held at First Presbyterian Church, located at 304 West Main St. in Lebanon.

The Bureau of Alcohol, Tobacco, Firearms and Explosives, the FBI, state fire marshal's office and Wilson County Emergency Management Agency are among those investigating.
